: We moved into a house that needs to have a water supply line connected to the meter tap. The meter tap is 3/4 and there is already a 2" line in place. If I go from 3/4" (at the tap) to 2" (supply line) to 1/2"
: (in the house) will this cause a problem with the pressure?

Jeff,
the 3/4" meter is pretty standard.
Having a 2" water line is a bonus, most of them are 1"
You can check the water sizing link below for more information. Terry
